If I had to choose between a Nav/250 and non-Nav/350, I'd go with the 350 every time. Wait a minute . . . I DID!

Try to find a CPO if you're concerned about repairs. Also, nearly any car you buy will still be under the factory 4yr/50k. If so, you can extend that through any dealer and there are dealers that discount this as well.

If you purchase a CPO car, you can trade in your current ride and save the hassle of a private sale. That's what I did and they gave me a fair price for my 330.

Good luck!

 

If ur a speed freak, take ur time and save some money for the 350, if not the 250 wud do just fine.

 

You can add aftermarket nav to a non-IS350 that does more than the factory unit and costs thousands less.

Try saying the same for adding power to a 250 :P

 

Yep. same reasoning here. SoCal rush hour you don't need, or should I say, wouldn't be able to use the extra 100hp.
